I really liked this quiz, but it would be useful to state in the description that this is specifically for the Rider-Waite. There are many tarot decks that use different names for the majors. You could attempt to go through and allow different names (i.e. for the first card you could allow Mage, Magus, and so on), but it's probably best just to specify that the quiz is about the Rider-Waite.
I only know Austrian Tarot and XXI is called "Mond" (Moon) here. I knew that the name originates from French "Le Mond" which mean "The World", so that is the only answer I got, because Pagat, Uhu, Kakadu and Quapil were obviously not present in an English tarot deck.
